Does lisinopril 25 mg HCTZ 20mg cause weight gain?

It did for me! I had an allergic reaction to something, probably the lisinopril. I ended up in the ER with hives, tightness in the chest/esophagus, and difficulty swallowing. I was given an epi pen shot, Benadryl via IV, and a Rx for prednisone when I was released. They also did the bloodwork for a heart attack. I immed. went off the lisinopril. I should have gained weight this past week as the steroid is suposed to cause fluid retention. Instead, I dropped four pounds and my bloated abdomen returned to normal. I supect I was really retaining fluids with the lisinopril. I was excercising quite a bit and couldn't lose weight. The nurse in the E.R. told me that they see 2-3 people a week with allergic reactions to ACE inhibitiors, of which lisinopril is one. My internist also said that the reaction was most likely from the lisinopril. I was on it for about two years before this occurred. The effects can really creep up on you-lethargy, weight gain, foggy thinking, sore legs. I believe this is a very dangerous drug.
